I was driving and i felt a jerk in first gear. After that my car started driving very roughly and i started to smell gasoline. when i approached a stop sign and stopped, my idles dropped way below the normal. the normal idle is 1500, it dropped to 250-500. I had a quarter of a tank, and after 15 minutes of driiving my tank was almost empty. Also really thick black smoke was comming out of the exhuast. i opened the oil cap, and checked the oil which turned outto be very dark. I also smelled gasoline very strongly from the oil. What is wrong with my car? please help!!!
-thanks
